Eggnog Tarts: Creamy Custard in Crisp, Buttery Pastry

Eggnog tarts are individual pastries filled with a smooth custard flavored with eggnog, nutmeg, and vanilla. A crisp, lightly sweet homemade crust balances the creamy filling, making these festive tarts a lovely dessert for a holiday table or a make-ahead treat for guests.

Ingredients

1½ cups (190 g) all-purpose flour, plus a little more for rolling
⅓ cup (40 g) powdered sugar
¼ teaspoon (1.5 g) fine salt
10 tablespoons (142 g) cold unsalted butter, cut into small cubes
1 large egg yolk (about 18 g)
1–2 tablespoons (15–30 ml) cold water, as needed
1½ cups (360 ml) eggnog, preferably full-fat
⅓ cup (67 g) granulated sugar
2 large eggs (about 100 g without shells)
2 large egg yolks (about 36 g)
1 tablespoon (8 g) cornstarch
1 teaspoon (5 ml) vanilla extract
½ teaspoon (about 1 g) freshly grated or ground nutmeg, plus a little more to serve
⅛ teaspoon ground cinnamon
⅛ teaspoon fine salt
1 teaspoon (5 ml) milk, for brushing the crusts (optional)

Instructions

Make the pastry. Whisk the flour, powdered sugar, and salt in a large bowl. Add the cold butter and rub it into the flour with your fingertips, or pulse briefly in a food processor, until the mixture resembles coarse crumbs with a few pea-size pieces. Stir in the egg yolk and 1 tablespoon (15 ml) cold water. Squeeze a little dough together; if it is still dry and crumbly, add the remaining water a teaspoon at a time. Stop as soon as the dough holds together. Press it into a flat disk, wrap, and refrigerate for 30 minutes. Chilling firms the butter so the pastry is easier to shape and less likely to slump in the oven.
Heat the oven and shape the tart shells. Heat the oven to 375°F (190°C). Lightly butter twelve 3-inch (7.5 cm) tartlet pans. On a lightly floured surface, roll the dough to about ⅛ inch (3 mm) thick. Cut twelve rounds large enough to line the pans, rerolling scraps once if needed. Press the pastry gently into each pan without stretching it, then trim the edges. Prick the bottoms several times with a fork. Arrange the pans on a baking sheet and refrigerate for 5 minutes while the oven finishes heating if the dough has become soft.
Blind-bake the shells. Line each pastry shell with a small square of parchment and fill with pie weights or dried beans. Bake for 12 minutes, then carefully lift out the parchment and weights. Bake for 3 minutes more, until the bases look dry and the edges are just beginning to turn pale gold. Brush the bases lightly with milk if you like a little extra browning; it is optional and does not seal the pastry completely. Let the shells cool in their pans for 10 minutes. Reduce the oven temperature to 325°F (163°C).
Mix the eggnog custard. In a medium bowl, whisk the granulated sugar and cornstarch until evenly combined. Whisk in the eggs and yolks until smooth, then slowly whisk in the eggnog. Add the vanilla, nutmeg, cinnamon, and salt. Pour the mixture through a fine strainer into a jug if you want an especially smooth filling; straining also catches any small bits of egg that did not blend in. Avoid whipping in lots of air, which can leave bubbles on the finished tarts.
Fill and bake. Set the tartlet pans on the baking sheet. Divide the custard among the shells, leaving a little space at the top so the filling does not spill as you move the tray. Bake at 325°F (163°C) for about 18–22 minutes. Begin checking at 18 minutes: the edges should look set, while the centers may still wobble slightly when the pan is nudged. Because this is an egg dish, check the center of a tart with a food thermometer; the USDA FSIS safe minimum internal temperature is 160°F (71°C). If it has not reached that temperature, bake for a few more minutes and check again. Avoid baking until the custard is completely rigid, as it will firm further as it cools.
Cool before serving. Transfer the pans to a rack and let the tarts cool for at least 60 minutes. The filling will settle and become easier to unmold as it cools. Carefully remove the tartlets from their pans, loosening the edges with a small knife only if needed. Finish with a light grating of nutmeg just before serving.

Tips

Keep the pastry cool. If it becomes sticky while rolling or shaping, refrigerate it for 10 minutes rather than adding lots of extra flour. Too much flour can make the crust tough, while warm butter is more likely to melt before the pastry sets.
Use full-fat eggnog for a rich filling. Reduced-fat eggnog works, but the custard will taste lighter and may be a little less silky. If your eggnog is strongly spiced, reduce the added nutmeg and cinnamon so the flavors do not overwhelm the vanilla.
Measure the filling into the shells carefully. A small jug or a measuring cup with a spout makes it easier to divide the custard evenly. If a little filling spills onto the pan, wipe it up before baking; baked custard can stick and make the tartlets harder to lift.
Watch for gentle movement, not a liquid center. The filling should tremble as one soft mass, not ripple like liquid. Use the thermometer to confirm 160°F (71°C), and avoid relying on color alone; eggnog custard can remain pale even when cooked.

Serving Suggestions

Serve the tartlets at cool room temperature or lightly chilled, with freshly grated nutmeg over the top. A spoonful of softly whipped cream is a simple accompaniment; keep it plain or add a small splash of vanilla. For a dessert plate, pair one tart with sliced pears, orange segments, or tart berries, which provide a bright contrast to the sweet custard. These are rich enough to serve individually after a holiday meal, but they also work well on a dessert tray alongside cookies or fruit. Set them out shortly before serving so the crust stays crisp, and offer a small fork or dessert spoon.

Variations

Use store-bought pastry: For a quicker version, use enough ready-made sweet shortcrust pastry to line twelve 3-inch tartlet pans. Follow the package directions for blind-baking, then continue with the filling and bake at 325°F (163°C). The crust may be less buttery or sweet than the homemade one, depending on the pastry you choose.

Make a larger tart: Press the pastry into one 9-inch (23 cm) tart pan and blind-bake it as directed, adding a few minutes if the base still looks damp. Pour in the custard and bake at 325°F (163°C), checking the center for 160°F (71°C); a larger tart may need several additional minutes. Leave extra time for it to cool before slicing.

Adjust the spices: Add a pinch of ground cloves or allspice for a more pronounced holiday spice note, or use only nutmeg for a cleaner eggnog flavor. Add spices sparingly because their flavor becomes more noticeable as the custard bakes.

Make them dairy-free: Use a dairy-free eggnog and a dairy-free baking stick in the pastry. Check that the eggnog is suitable for cooking, and expect a modest change in richness and flavor; different plant-based drinks vary in sweetness and thickness. Keep the eggs in the filling, since they provide its custard structure.

Storage and Reheating

Cool the tarts, then refrigerate them in a covered container within 2 hours of baking. They keep well for up to 3 days in the refrigerator; the pastry gradually softens as it absorbs moisture from the custard. For the best texture, place parchment between layers if stacking, or store them in a single layer. These custard tarts are best served chilled or brought to cool room temperature, so reheating is not necessary. If you do warm one, use a low oven for just a few minutes and serve promptly; microwaving can make the custard rubbery and soften the crust. Do not leave them at room temperature for more than 2 hours. Freezing is possible, but thawed custard may become slightly watery and the pastry less crisp, so refrigeration is preferable.

Frequently Asked Questions

Can I make eggnog tarts ahead?
Yes. Bake them a day ahead, cool completely, and refrigerate covered. For a crisper crust, you can bake the pastry shells a day ahead and store them at room temperature in an airtight container, then fill and bake the custard on the day you plan to serve. Once filled and baked, keep the tarts refrigerated.

Why did my custard crack or turn grainy?
Custard can become grainy or crack if it is baked too long or at too high a temperature. Keep the oven at 325°F (163°C), start checking at 18 minutes, and take the tarts out once the centers reach 160°F (71°C) and are softly set. They will continue to firm as they cool.

Can I use eggnog straight from the refrigerator?
Yes. Cold eggnog is fine to use; whisk it in gradually so it blends evenly with the eggs and sugar. The cold filling may take a little longer to bake than a room-temperature mixture, so use the temperature and visual cues rather than relying only on the clock.

How do I keep the pastry from getting soggy?
Blind-bake the shells until their bases look dry before adding the custard, and allow the shells to cool briefly so the filling does not warm the pastry. Fill them just before baking rather than letting the uncooked custard sit in the shells. For the best texture after baking, serve within a day, though the tarts remain good refrigerated for up to 3 days.

Can I make these without individual tartlet pans?
A standard muffin pan can work, but its wells are usually deeper and narrower than tartlet pans, so the shape and baking time will differ. Line the wells with pastry, avoid overfilling, and begin checking early; confirm the center reaches 160°F (71°C). A single 9-inch tart pan is another convenient option.

What kind of eggnog should I choose?
Use plain, ready-to-drink eggnog rather than eggnog-flavored coffee creamer, which may have a different thickness and sweetness. Full-fat eggnog gives the smoothest, richest custard. If the carton is already heavily spiced, taste a small amount and reduce the added spices to suit it.
